LTC1864ACMS8#TRPBF

LTC1864ACMS8#TRPBF is a µPower, 16-Bit, 1-channel ADC converter. The supply current drops at lower speeds because the LTC1864 automatically power down between conversions. This 16-bit switched capacitor successive approximation ADC includes sample-and-holds. The LTC1864 has a differential analogue input with an adjustable reference pin. With its 3-wire, serial I/O and small package, it offers an extremely high sample rate-to-power ratio, making it an ideal choice for compact, low-power, high-speed systems. This ADC can be used in ratiometric applications or with external references. The high impedance analogue inputs and the ability to operate with reduced spans down to 1V full scale allow direct connection to signal sources in many applications, eliminating the need for external gain stages. Applications for the LTC1864 include high-speed data acquisition, portable or compact instrumentation, low-power battery-operated instrumentation, and isolated and/or remote data acquisition.
